abstract: Let $(M,g)$ be a $n-$dimensional compact Riemannian manifold. Let $h$ be a smooth function on $M$ which has a local maximum point $\xi$ such that $h(\xi)=0.$ We find conformal metrics $g\lambda$ whose scalar curvature is the prescribed function $h\lambda:=\lambda2+h$ where $\lambda$ is a small parameter. The metrics $g\lambda$ blow-up at the point $\xi$ as $\lambda$ goes to zero. The result is obtained in collaboration with Carlos Roman (UPMC Paris)
